Flat rooflights for Bicester homes
A single near-flat pane on an upstand: minimal, low and discreet.
On the shortest day Bicester gets about 7h 45m of daylight, with the sun only 14.7° above the horizon at noon. Light from the sky overhead is the brightest available in winter, which is exactly what a roof lantern collects.
- Fixed or electric opening versions
- Minimal, frameless-looking from inside
- Usually cheaper than a lantern

Planning and building regulations for Bicester
England's Approved Document L caps the U-value of new or replacement rooflights in existing homes at 2.2 W/m²K, calculated with the glass horizontal.
Lanterns on permitted development extensions are part of the extension's height limits. Adding one to an existing roof is different: over 150 mm of projection can mean a planning application.
Building regulations in Bicester are checked by your local authority building control team or a registered building control approver. Replacing a rooflight in an existing home is building work. Installers registered with a competent person scheme can self-certify; otherwise building control must be involved.
